Family/Systemic Therapy

Family/systemic therapy emerged in the 1950s and 1960s as a radical paradigm shift in the understanding of psychological problems. Rather than locating pathology within the individual, the systemic approach places it in the interaction patterns among members of the family system. This perspective draws on general systems theory (von Bertalanffy), cybernetics (Wiener, Bateson), and communication theory (Watzlawick). The concept of circular causality replaces linear causality: in a system, each member's behavior influences and is influenced by the behaviors of others in a reciprocal and recursive manner.

Several schools contributed to the development of systemic therapy. Salvador Minuchin founded structural therapy, centered on family organization: hierarchies, boundaries between subsystems (parental, sibling), coalitions, and triangulations. Jay Haley developed strategic therapy, focused on the interaction sequences that maintain the symptom and on the use of paradoxical prescriptions. The Milan school (Selvini Palazzoli and colleagues) introduced the invariant prescription and circular questioning. Murray Bowen proposed multigenerational theory, with concepts such as differentiation of self, emotional triangles, and multigenerational transmission of patterns.

The concept of family homeostasis — the system's tendency to maintain its equilibrium — explains why one member's symptoms (the 'identified patient') may serve a stabilizing function for the system as a whole. For instance, a child's symptomatology may deflect attention from unresolved marital conflict. Systemic therapy seeks to disrupt dysfunctional patterns and facilitate new forms of interaction that allow the system to reorganize in healthier ways.

Research has supported the efficacy of family/systemic therapy for a wide range of problems. Carr's review (2012) documented solid evidence for conduct disorders in children and adolescents, eating disorders, couple problems, substance abuse, and relapse prevention in schizophrenia. Family therapy is particularly relevant when the relational context is a significant maintaining factor, when an individual's symptoms serve a systemic function, or when change requires the collaboration of multiple system members.
